RNA that nearly self-replicates offers new clues to life’s origins
A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early Earth, according to a study published in Science in early 2026. The ...
In a study published in the journal Clean Water on March 28, scientists reported that extracellular RNA (exRNA) from bacteria can persist in disinfected drinking water. They also found that by ...
The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

Study: RNA drugs work best when they reshape RNA, not just bind to it
Researchers led by Davide Incarnato at the University of Groningen have demonstrated that the FDA-approved cancer drug ...
Ancient DNA has been pulled from a permafrost-preserved woolly mammoth found in Siberia, and scientists are thrilled. They recovered and sequenced RNA, a fragile molecule that many biologists assumed ...
Ribonucleic acids (RNAs) serve as messengers between DNA and protein production, and perform a wide variety of regulatory functions across different cellular processes. This makes them an interesting ...
People are still debating whether the mRNA from COVID-19 vaccines remains in the body longer than it should. Some say it lingers and causes harm, others say that idea just doesn’t hold up. A new ...
